Have no space? Check these out

I own one Infinity Reference 850W Subwoofer, have it in a ported (10"x14"x14") enclosure box hooked up to a Crunch p900.4 (900W).
I own a Astro Mini-Van and place the enclosure between the rear bucket seats and it beats hard. But I recommend having two of these babies and they'll here you coming. you don't need 15" subwwofers to have that BOOM, this subwoofer will do fine.

Bass in Small Package

The Infinity 850w 8" Subwoofer is great for a 14"x10"x10" bandpass enclosure. I recommend this product if you lack space and want that deep bass.

Awesome

I just bought a pair of these for my 2004 silverado extended cab truck. I made two custom (ported) enclosures that fit under the back seat with the drivers facing towards the sides of the truck. I have about .6 cubic feet and they hit very tight and hard. I was quite surprised. They lack a little on the bass below about 60hz but i may try to increase the size of the enclosure slightly. I just used a high/low adapter to wire the amp to the stock bose system and it really cranks. A great option for people who dont want to go crazy in their trucks but want a nice bass addition. If your musical taste is rock, metal, or club type music these will shock you. If you are looking for the very low boom bass in extreme volumes you prob better use at least a 10 inch depending on the application. Anyways, I am very satisfied with these speakers and i am somewhat an audiophile so for anyone interested give them a try you wont be sorry.

Nice little sub

Sounds great. I installed in a very small box (0.27cf). Much heavier than I expected.
